Systems and methods for service restoration for satellite communications resilience

Abstract

A method for satellite communications network resiliency comprising, at a satellite service provider computing system: identifying a set of lost links between user terminals of a satellite communications network, wherein the lost links are due to a loss of at least one beam of the satellite communications network; determining a repointing of at least one user terminal to restore at least a portion of the lost links by using one or more optimization algorithms to determine a set of one or more user terminal repointings that maximize a reward based on the set of lost links and a network graph and a beam graph associated with the satellite communications network; and instructing repointing of the at least one user terminal.
